The problem

• We want to define and enforce a style guide for Symfony commands (see [DX] Improve the output of all Symfony commands #11784)
• There is already a proposal for this style guide ([RFC] The Symfony Console Style Guide symfony-docs#4265)
• We need to make it really easy to follow the style guide once it's approved.

The solution

The first obvious proposal would be to add more helpers to FormatterHelper, such as formatTitle(), formatSectionTitle(), formatList(), formatDebugInfo(), formatNoteBlock(), etc.

Anyway, I would prefer to read your opinions about better and more concise solutions.
